Cellular product and method of making the same



- Patented Feb. 11, 1930 PATENT OFFICE MAX GR'UNBAUM, OF BROOKLYN, NEWYORK CELLULAR PRODUCT AND METHOD OF MAKING THE Ho Drawing.

This invention relates to cellular products such as paper, wall paper,paper board, paste board and like materials produced from paper or likecellular pulp, containing as a constituent part thereof an insecticidal,germicidal and fungicidal material which is non-' odorous,non-poisonous, or substantially or relatively non-poisonous to mammalsand which can be added to the pulp from which such products are madewithout causing any material deterioration thereof and which issubstantially unaffected in the process of producing such products fromthe pulp treated therewith. p The invention is more particularlyconcerned with paper, paper board, paste board, and like materialsproduced from paper, but primarily wall paper, treated in accordancewith this invention to render such products insect, germ and fungusproof. The invention also relates to the process of roducing suchinsect, germ and fungus proo products. It is well known that for manyuses paper and other cellular products of the character referred toabove have been found to be highly objectionable because of the factthat such products are subject to injurious attack by insects and fugiand also because certain paper or pulp products such as wall board andwall paper are unsanitary and provide breeding laces for germs, insectsand the like. These ob ectionable features, particularly the .latter inregard to wall paper, have resulted in the discontinua nce of the use ofcertain paper products with consequent loss to manufacturers of suchproducts.

I have discovered that these objectionable features can be obviated andthat satisfactory insect, germ, and fungus proof products can be made byincorporating a non-odorous insecticide, germicide and fungicide whichwill not injure or be injured by paper or like pulp with the materialsfrom which the products.

are to be produced, before forming the products or applying suchprotective material to the finished product. I prefer to employ anorganic insecticide, germicide and fungicide and of such organicinsecticides I prefer to use an organic insecticide which has beenderived from the bark of the cinchona tree here- Application filed May8, 1928 Serial No. 276,203.

inafter referred to as a cinchona derivative. Among the materials soderived and which are particularly adapted for use in the practice of myinvention, may be mentioned quinine, quinidine, cinchonine andcinchonidine. Although all of these materials, or anyone of them, may beemployed with success, Iprefer to use cinchonine (C H N O) or its salts.These materials, in addition to being odorless insecticides aregermicides and fungicides as well, and are non-poisonous or at the mostonly slightly poisonous to mammals. The taste of these materials isextremely bitter and offensive.

In the preferred ractice of my invention I mix about 0.04 of a pound ofcinchonine with each 100 pounds of the cellular material which forms thestock from which the insect proof article is to be produced. Afteradding the insecticide to the pulp or stock, the paper, 70 paper board,wall paper, paste board or'the like is produced in any usual or desiredmanner and the product is not deleteriously affected by the presence ofthe cinchonine and the cinchonine is not deleteriously affected by theprocess of producing the paper or the like from the thus treated pulp.

In producing paper and like products which are insect proof, germ proofand fungus proof according to my process, the insecticide may not onlybe-added to the materials from which the paper, paste board or the likeis to be formed but it may be added to the clay or other filler or sizewhich may be employed in or upon the surface of the paper or the like.In addition, the protective material may be incorporated in the coatingmaterial when s'o-called coated papers are being produced. Also, in thecase of wall paper and other paper products which are substantiallycompletely covered with a printed design I may advantageouslyincorporate the protective material in the printing ink and impregnatethe'paper product with such material during the printing thereof.

In place of cinchonine or other cinchona derivative I may with somemeasure of success employ sodium fluorid or a silicofluoride but Iprefer touFe a cinchona derivative.

As heretofore stated, my invention is preferably emplo ed in themanufacture of wall described having cinchonine incorporated paper andli e cellular wall coverings and therein.

when so used the cinchonine or equivalent material is preferably addedin the proportions set forth to the pulp, filler, size, printing ink orthe like used in producing the wall cover- Ily invention is alsoparticularly adapted for use in preparing paper products for packagingfood and other materials which are subject to deterioration due to theattacks of insects, germs, fungi and the like.

While I have described in detail the preferred practice of my processand the materials which I prefer to employ it is to be understood that Iam not limited thereto except as set forth in the subj oined claims.

I claim:

1. The herein described process of making products roduced from cellularmaterial insect proo which comprises incorporating a cinchona derivativetherein.

2. The herein described process of making 4. The herein describedprocess of making insect proof, germ proof and fungus proof wall paperand like cellular material which comprises adding a cinchona derivativeto the material from which such products are formed, and forming thepaper and like cellular material therefrom.

5. The herein described process of making insect proof, germ proof andfungus proof Wall paper and like cellular material which comprisesadding a compound of the quinine group to the material from which suchproducts are formed, and forming the paper and like cellular materialtherefrom.

6. The herein described process of making insect proof, germ proof, andfungus proof wall paper and like cellular material which comprisesadding cinchonine to the material from which such products are formed,and forming the paper and like cellular material therefrom.

7. The herein described process of producing insect proof papercomprising adding a cinchona derivative to the material from which suchproducts are produced, and forming the paper therefrom.

8. The herein described process of producmg insect proof papercomprising adding cinchonine to the material from which such productsare produced, and forming the paper therefrom.

9. A cellular product of the character described having a cinchonaderivative incorporated therein.

10. A cellular product of the character In testimony whereof I aflix mysignature.
